To :i1/ZZ wtom it may concern: l Bc it known that I, GILBERT W. Snnanv, a citizen of the United States, residing' in the borough ci Manhattan, in the city of New 5 York, in the State of New York, have invent- V ed certain new and useful Improvements in 'iypeililriting Machines, of which the lfollowing is a specification, reference being, had to the accompanying drawings, forming a part 1o hereof.

This invention relates to typetvriting ma chines such as are sometimes used -for the amusement and instruction of children and are also sometimes used for practical purposes when great speed in writing is not reuuired. 1

The object of the invention is to produce a tj,fpeWrit-iug machine of this cliaracter which shall he simple in construction and yet well adapted for accurate and fairly rapid work,

and shall also he readily convertible from a platen-machine to a machine of the boolr typewriter variety, or vice versa.

rilie invention Will loe more fully explained $5 hereinafter With reference to the accompanying drawings, in which it is illustrated as ern-e bodied in a convenient and practical con struction, and in which Figure l is a view in iront elevation of a la? vtypewriting machine constructed in accord# tance with the invention. a

view thereof. Fig. 3 is a rear elevation thereci. Fig. 4 is a view intransverse section at the left of the hammer and feeding devices in $5 `Fig. i looking toward the right.

.in the machine shown in the drawings, a suitable base c supports, near the ends thereof, standards b, in which is mounted for rotation vthe usual cylinde1platen c, provided at one end with a suitable operating-Wheel or handlc d. A cooperating presserfroll e is also mounted in the standards b, and upon the base cinay be secured a guard-plate of. Removably secured upon the standards l) is a bed-plate f, which supports the printing devices and is made removable in order that the printing devices may be used in the manner of a book type-writing machine. As a convenient means of securing the bed-platef Fig. is a plan `50 removably upon the standards b thelatter peccafcn of Letters Fatent.

are provided with upwardlyprojacting lugs t', which are extended through suitable slots in the edges of' thebed-plate f and are en", ga ed by retaining-pins liz. ,i

pon the bed-plate fis 4hinged at therear edge thereof a carrying-plate g, upon which the printing devices are mounted, said plate g being hinged 'so that it can he turned hack at any time with the printing devices to ein Written upon, The front and rear edges of the carrier-plate g" are turned over, as at g and g2, to form. guides for the traveling plate h, upon Whichthe printing devices are di rectly mountr-id.k As shown in the drawings, suitable standards "L are erected upon the thcspools lc, ,the shaft of one of said spools being provided With a Wheel or handle lc', by which it may he rotated. An endless typebelt Z is-supported by the spools bearing the type m upon its outer surface, While upon its inner surface may be marked indications of the type. The traveling plate h is preferably cut away, as at h', to expose the platen c or the surface to be printed upon but extending longitudinally ofthe opening h. is a flanged type-guideway 1t, to hold the type from accidental displacement, such guideway being formed with an opening u at the point of printing of the proper size to permit one of the type to beforced through the opening into con tact Wi th the paper to be printed upon. lnking padso may be secured to the traveling late h near the spools lc for contact with the taces of ,the type, as the belt is moved by the hand of the operator. Apointerp, secured to the traveling plate, indicates to the operator the correct posi-tion of the type which is to be brought in contact with the printing-surface. To eiiect the proper pressure upon each printing-point and also to effect the proper xm ovement of the carrier-plate for the s acing of successive letters, Athere is pivote upon the standards i at the right-hand end of the traveling plate 7i a lever orrame vq, which carries at'itsforward end on its under surface i a stud r to serve as a type hammer or plunpose the platen or the surface of the paper type as it is brought by the operator to the traveling plate it, near the ends thereof, and, in such standards are mounted for rotation l lOO Uvi

ger, it being properly placed with relation to the opening n in the type-guide, so that u on de ression of the lever the type which is t en in ine with the opening n is pressed through the opening by pressure upon the inner surtace of the belt into contact with the printing-surface to make an impression thereon. The lever or i'rame may be Aprovided with legs q q2 for contact with the traveling plate h to prevent excessive' pressure on the type. Pivoted to the lever q is a feed-pawl s, adapted to engage the notches formed in the e ge of; the ilange g2, which thus constitutes a feedrack. Alfspring t' draws the pawl s back after each'bperation, and as the end of the pawl rests .upon the travelingplate h the spring also serves, -acting through the pawl, to raise the -type-lever q after Ieach operation. this manner the pawl after each operation is brought into engagement With the next successive tooth of the rack g2, and upon depres-- sion of thetype-lever through the pawl stile -1 traveling plate bearing the printing devices is moved one step farther toward the right. A handle u is secured to the pawl s and is brought to the'ront ofthe printing mechanism, so that it can be readily grasped by the operator and the pawl sv` pulled out of engagement with the rack g2 Wheneverit is desire-d' to move the printing devices'in either direction without actuating the type-lever. 'lne extentfof upward 'movement of the forward end of the lever q, and consequently the torwardmovement of the bpalwl s, ,are limited by cgntact of the rear end thereoi` witlithe traveLiug plate it.

nevertheless the printing mechanism, with the bed-plate, can be readily detached from the rest of the machine and used as a book type-Writer. It wi l be understood, of course, that various changes in details may be made 'as may be desiredl yand that the invention is not restricted to the precise construction and arrangement of parts shown and describedherein.
